Questions on the Study of Bullet Trajectories and Firearm Identification

In the realm of firearms, there are various types and mechanisms that play a significant role in their operation. One such mechanism is the pump action, also known as slide action, which is commonly found in various firearm designs.

Homemade or improvised firearms, often referred to as zip guns, are another intriguing subject. These firearms are typically assembled from parts of other firearms, creating a unique and often dangerous weapon.

The SVDM SVK Kalashnikov sniper rifle, mentioned in some discussions, is manufactured by the Kalashnikov Concern, a well-known name in the firearms industry.

Forensic analysis plays a crucial role in linking a fired cartridge case to a suspect firearm. This is done by examining ejector marks, extractor marks, and firing pin impressions on the casing. However, it's worth noting that the maker's mark is not found on the fired cartridge case.

The number of lands and grooves in a 32 revolver is six, a characteristic that can influence the bullet's trajectory. The diameter of the 16 bore shotgun and the 8 bore shotgun, on the other hand, are not specified in the provided information.

Bullet wipe, the mark left on the inside of the barrel by the bullet as it is fired, is an important aspect of forensic analysis. Burning, blackening, and tattooing can also be useful for determining the type of gunpowder used in a fired bullet.

The 7.62 mm AK-47 assault rifle, a popular choice worldwide, has a magazine capacity of 30 rounds. Dumdum Bullets, known for their lack of a hollow point, expand upon impact, making them particularly dangerous.

Tandem Bullets, designed to fragment upon impact, creating multiple projectiles, are another type of ammunition. These bullets are not specified in the provided paragraph.

Wads and cushion wads, found in shotgun cartridges, serve to separate the shot from the powder charge and to seal the breech. In a firearm case, the minimum velocity required to perforate human skin with a 0.22 Airgun pellet is not specified.

Ram rods, a part of muzzle-loading firearms, are used to push a bullet or shot into the barrel. The shortening of the barrel increases the dispersion of pellets in a shotgun, due to less pressure inside the barrel.

In shotguns, the dispersion of pellets is more in the true cylinder gun than in a choked gun, due to the lack of constriction in the true cylinder barrel. The terminal velocity of a 9 mm bullet is not specified in the provided paragraph.

Rifling marks on fired bullets are of the helical grooves type. The ejector is not present in a single-shot firearm. The trigger pull of a double action revolver is not specified in the provided information.

In forensic analysis, the modified Griess Test is specific for the determination of nitrates in gunpowder residue. In a firearm case, the causality criteria for a person's death are the set of conditions that must be met for a firearm discharge to be considered the cause of the death.

Finally, it's interesting to note that in bullet projectory, the maximum range can be attained if the angle of projection is 45 degrees. Gelling agents added to explosive mixtures to improve their resistance to moisture and increase viscosity are known as plasticizers. Cutting of the barrel has no effect on the dispersion of pellets on a target, as it only affects the bullet's trajectory.
